moldcatGruber offers an extensive selection of high quality standard production molds to fit your cultured marble, solid surface, or other cast polymer production needs.

No amount of manufacturing ingenuity can take the place of a quality hand-crafted mold. Gruber has produced the highest quality molds for almost 40 years for a variety of composites manufacturing applications. The integrity of our products is the result of careful procedures and strict controls. All incoming raw materials are tested to ensure that only quality raw materials are used. Quality control inspections are made four times during our production process, with a final inspection made just prior to shipping.

Mold Terms of Sale and Warranty

Which mold construction method is right for you - Metamold, or Vinyl Ester? Review this before placing an order for a Gruber mold!

Should you buy a female mold, or use "hats" (permanent hats or reusable hats) - review this before you order!

Custom Designed Molds and Proprietary Molds - In addition to these in-house projects, our designers can work directly as your consultants. You can generate new designs in two ways: by requesting a custom mold for your own exclusive product, or by requiring modifications of our standard catalog molds. Over the years our mold appearance may look much the same, but the molds have changed substantially, reflecting the newest materials and construction techniques.

Slip Resistance Data - Review test data demonstrating compliance with ASTM F462-1994 standards. This test data applies to all Gruber shower molds or tub molds equipped with a textured floor surface, as well as selected other molds.
